This invention relates to implement carrier frame, and more particularlyrelates to an adjustable implement carrier frame for tractors whereby acotton harvester or other implement may be mounted on a motor vehicle,such as a tractor, for operation and use.

It is quite usual to mount agricultural implements or machines ontractors by means of suitable carrying and mounting members which areattached to and supported by the tractor. However, different makes anddifferent models of tractors vary from each other in size and in thesizes of their various parts; and heretofore the machine or implementmounting and carrying attachment means that have been provided have beenof such design that they fit and can be used with only one particularsize of tractor or one particular size of tractor part to which itsmembers are attached. Accordingly, different implement carrier frameshave been required for the different makes and types of tractors.

It is a principal object of this invention to provide an implementcarrier frame for supporting a harvester or other machine or implementon a tractor, the frame being adjustable to fit and to be attached totractors of different sizes and types, thus eliminating the necessity ofproviding separate and different implement carrier frames for thedifferent sizes and types of tractors.

Another object of this invention is to provide an adjustable carrierframe of the character described, and a carrier frame which is suited tomount and support different kinds of machines or implements on atractor.

Another object of this invention is to provide a carrier frame of thecharacter described and which is strong, sturdy and durable, provides avery firm, tight and strong attachment to the tractor and afiords astrong, steady and firm support for the machine or implement that ismounted thereon.

Another object of this invention is. to provide a carrier frame of thecharacter described and which may be adjusted quickly and easily to beattachable to different sizes of tractor parts to which the attachmentis to be made; and can be attached to and mounted on or dismounted froma tractor readily and easily.

A specific object of this invention is to provide an adjustable carrierframe of the character described and which is attachable to tractor axlehousings of different cross-sectional dimensions and shapes.

Other objects of this invention will be in part obvious and in partpointed out hereinafter.

ings of different cross-sectional dimensionsand shapes, as occurs indifferent sizes and models of tractors, so that the carrier frame can beused with tractors of different makes and models among Which thecross-sectional dimensions and shapes of the axle housings differ.Supported on" and pivotally secured to each of these clamps is an undergirder arm extending rearwardl from the clamp, the swinging connectionof the girder arms to the clamps permitting the arms to be adjustedtoward and from each other to accommodate therebetween tractortransmissions of different widths, as occur in tractors of differentsizes, makes and models. A pair of supporting bars extend across and aresupported on the two under girder arms, one toward the rear ends of thegirder arms and the other spaced forwardly from the rear supporting bar,and means are provided on the under girder arms and. the supporting barswhereby these arms and bars may be fastened together in the adjustedpositions of the girder arms on their pivots relatively to each otherand in different positions into which the supporting bars have beenadjusted on the girder arms longitudinally thereof. The supporting armsare adapted to have mounted thereon and to support a cotton harvester orother machine which preferably has a base'or framework that may beplaced on the supporting arms; conven tional means being'employed toanchor the harvester or other machine to the supporting bars of themounting. By adjusting the supporting bars on the girder arms toward oraway from the power take-off shaft of the tractor the driving ed to theaccompanying drawings forming a part:

Similar reference characters refer to similar parts throughout theseveral views ofthe dra'wed'to renamed tightly and firmly on the axleliousmg H by means of @holts 13 which extend between the channel 10 andplate .12 .above'the axle housing and bolts 13 which extend between the:channel l .and the plate '12 ibelowthe axle lt isreadilyapparent thatthese clamping ineans may he applied to Laxle housings .of different.cross sectional dimensions as welllas toaxklelhousingsofrdifferent'crosssectionalshapes such as'round, square and hexagonal."To the base-ll of (each channel "member 10 .is secured a hy welding rajournal Lb'lock M which has a vertical hole to receive .a bolt 1 5;.piv.ot.ally therein; ;the upper and lower ends .of the bolt extend ingthrough .bolt holes provided therefor in upper and lower ears .I 6 andL6 carried .on the end of achehhelshaped girder-arm I! which has its-web'- or base in vertical position.

.these two :girder arms Ll are supported two cross-supporting bars .18and'lra kwhich'extend across the .twoggirder farms I 1 and :areadjustable on the girder arms longitudinally "thereof, and are :adaptedto be secured thereto their (ad-- just edpositions. llhe-cross-isupporting 'bar 18 disposed itoward-lthe rear :ends of:thergirder arms l-l and the cross-supporting bar 19 .is spacedsamedistanceinwardlyifromfche bar l8.
